В отечественных нормах боковое давление грунта регламентируется определять для стадии, соответствующей образованию поверхности скольжения, что отвечает теории Кулона. При этом предельные величины давления грунта на гибкую стенку не зависят от характера и интенсивности деформаций подпорной конструкции. В связи с этим возникает необходимость совершенствования методов расчета ограждений для учета вышеуказанных факторов.</p></sec><sec><title>Цель работы</title><p>Цель работы: получение опытных данных для разработки метода расчета активного давления грунта на подпорные конструкции в зависимости от их деформаций.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Опытные работы выполнены методом физического моделирования для различных схем моделей гибких подпорных стенок с использованием специализированного лабораторного испытательного стенда. В качестве модельного грунта засыпки применялся песок средней крупности, определение физических характеристик которого производилось в лабораторных условиях в соответствии с ГОСТ 5180-2015.</p></sec><sec><title>Результаты</title><p>Результаты. Проведенные исследования позволили получить данные о характере деформаций грунта засыпки в пределах призмы обрушения для различных кинематических условий работы модели подпорной стенки и, соответственно, обосновать применение феноменологической модели наклонных блоков, использованной для разработки метода определения активного давления грунта на ограждающие конструкции.</p></sec><sec><title>Выводы</title><p>Выводы. Опытные исследования показали соответствие характера деформирования грунта засыпки и принятых условий работы грунта в рамках разработки инженерного метода определения бокового давление грунта. Полученные экспериментальные данные могут быть использованы в процессе реализации и верификации предлагаемого метода расчета, который позволит проектировать ограждения котлованов более обосновано и во взаимном соответствии с фактическими эпюрами давления грунта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The Russian standards determine the lateral earth pressure at the failure surface stage, which corresponds to the Coulomb’s theory. In this case, the limit values of earth pressure on the flexible wall remain independent from the nature and intensity of deformation of the retaining structure. Therefore, computational methods for retaining walls are to be improved considering the above-mentioned factors.</p></sec><sec><title>Aim</title><p>Aim. To obtain experimental data in order to develop a computational method for determination of the active earth pressure on retaining structures depending on their deformations.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Experimental tests were carried out by physical simulation for various models of flexible retaining walls using a purpose-designed laboratory test bench. Medium sand was used as a model backfill soil; its physical properties were determined under laboratory conditions in accordance with State Standard 5180-2015.</p></sec><sec><title>Results</title><p>Results. The tests provided data on the character of backfill soil deformations within the wedge of failure for different kinematic conditions of the retaining wall model and, accordingly, justified the application of inclined block phenomenological model, used to develop a computational method for determining the active earth pressure on retaining walls.</p></sec><sec><title>Conclusions</title><p>Conclusions. Experimental tests indicate the correlation between deformation nature of the backfill soil and accepted conditions of soil operation during the development of engineering method for determining the lateral earth pressure. The obtained experimental data can be used in adoption and verification of the suggested computational method that enables shoring of excavations to be designed more reasonably in mutual conformity with the actual earth pressure diagrams.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>активное давление грунта</kwd><kwd>гибкие подпорные стенки</kwd><kwd>экспериментальный анализ</kwd><kwd>численное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>active earth pressure</kwd><kwd>flexible retaining walls</kwd><kwd>experimental analysis</kwd><kwd>numerical simulation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья написана в рамках выполнения НИОКР за счет финансирования ФАУ «ФЦС».</funding-statement><funding-statement xml:lang="en">The article was written as part of the implementation of R&amp;D at the expense of funding from the Federal Center for Regulation, Standardization and Technical Assessment in Construction (FAU “FCC”).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">&lt;i&gt;Рубин О.Д., Лисичкин С.Е., Фролов К.Е., Пащенко Ф.А., Зюзина О.В.&lt;/i&gt; Экспериментальные исследования железобетонных подпорных стен.
